ROTARY MOTOR.

Application filed August 24, 1923, Serial No. 659,180. Renewed February21, 1928,

This invention relates toav rotarymotor, the general object of theinvention being to provide means for passing the air compressed by therotor through a carburetor where it will pick up a certain amount offuel and then leading it into a compression chamber which is providedwith a valve conrolled port where the gases resultant from the firing ofthe mixture in the said chamber will enter the cylinder and act againstthe abutments to give the rotor its momentum.

Another object of the invention is to provide cam operated means foractuating the sliding abutment and the valve which controls the portleading from the compression chamber to the cylinder, such means actingto prevent binding ofthe abutments and valve. z

A still further object o-f the invention is to cause the moving parts tooperate in a lubricant and to enclose the parts in a water jacket.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention indetail, reference will be had to theaccompanying drawings wherein like characters denote like orcor-responding parts throughout the sev eral views and in which Figure 1is an elevation of the invention.

Figure 2 is a view of one end removed and the parts in section.

Figure 3 is a longitudinal sectional view.

Figure 4: is asection on line 44 of Fig ure 2.

Figure 5 is a plan view.

Figure 6 is a view of the rotor.

Figure 7 is a section on line 7-7 of Figure 6.

Figure 8 is a detail view of the sliding abutment and the cam engagingmembers thereon.

In these views 1 indicates a cylinder and 2 the rotor therein, 3indicating the shaft to which the rotor is fastened. The cylinder isarranged in a casing 1 which forms an oil chamber and the shaft passesthrough the ends of said casing. The interioro f the rotor is incommunication with said chamber so that when; the chamber is filled withoil, said oil will circulate through therotor. The casing is providedwith an extension at in which is formed a combined compression andexplosionchamber 5 which is in communication with the interior ofthecylinder by a port 6, compressed air being led into the chamber 5 bymeans of the pipe 7 which is connected with the port 8 which enters thecylinder immediately in rear of the sliding abutment 9 the port 6 beinarranged in front of the abutment. A sliding valve 10 is arranged tocontrol the port 6 and this sliding valve is made similar to theabutment. Each of these parts are arranged to slide in achamher 11 andthe stem 12 e-n gaged by a coil spring 13 which is adjustable by meansof theset screw 14:. I A cross piece 15 is held against the upper edgeof. each member by av collar 16 and pins 17 are connected with the endsof each cross piece. The lower ends of the pins of the abutment engagethe cams 18 While the pins of the valve engage the cams 18. The cams arearranged on the shaft 3 and are so arranged that the abutment 9 will belifted just as soon as the piston 19 of the rotor starts to pass theport 8 andthe cams will lift the valve 10 just as the explosion istaking place in the chamber 5 and the pist0n19 has partly uncovered theport 6. A carbureter 20 is connected with the pipe 7 so that the airshown at 26 and the extension & is provided with a water chamber-27which is in communication with the water chamber for cool.- ing thechamber 5 and the valve. The check valve for the chamber 5 is shown at28.

From the foregoing it will be seen that the air previously drawn inthrough port'26 by the suction created by the moving piston 19 will becompressed in the space ahead of the piston when said abutment passesthe port 26 and said air will be led by the pipes 7 throught-hecarbureter and into the cha mher 5. As it passes through the carburetorit will be mixed with the vapors from the gasoline or other fuel thereinso that when the mixture reaches the chamber 5 it will be of anexplosive nature. The valve 10 will hold the mixture in a compressedstate in said chamber. Just before the piston 19 reaches the slidingabutment 9, said abutment will be raised by the cams to permit thepiston 19 topass it and then it will drop back into engagement with therotor. As soon as the piston 19 uncovers the port 6 the explosion willtake place in the chamber 5 and the" valve 10 raised to permit the gasesto act on the piston 19 and abutment 9 and thus give the rotor itspropellingstroke. When the piston 19 passes the port 26 the burnt gaseswill escape and air will bedrawn in as the piston 19 moves upwardly.

The ends of the casing and the ends of the cylinder are removable so as'to provide access to the parts.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several port with theinlet end of the carbureter, the,

lower part of the cylinder having a combined inlet and exhaust porttherein, a rotor in the cylinder, a piston therein arranged to close theports as it passes over the same, a sliding abutment in the casing andarranged between the upper ports which are connected respectively withthe carbur-eter and the combustion chamber, said abutment engaging therotor, a sliding valve for controlling the port leading to thecombustion chamber,

cams connected with the rotor means associated with the abutment andvalve and 015- erated by the cams for raising the abutment to permit thepiston to pass the" same and for lifting the valve as soon as the portleading to the combustion chamber is partly uncovered by the piston andmeans tor firing the charge in the combustion chamber ust before thevalve is opened. In testimony whereof I HARLEY D. WEED.
